comcast's nbc and cbs have also launched 24-hour sports networks. but where fox hopes to differentiate itself is with distribution and live sports rights. fox's speed channel already is in more than 80 million homes, and fox owns rights to mlb, nascar, college sports, and ufc. it's easy to understand why news corp wants to launch an all- sports channel. espn is worth $40 billion, nearly half of parent company walt disney company's total value. additionally, the channel rakes in more the $5 a month for every cable subscriber in 100 million households, regardless if they watch or not. but espn, like rome, wasn't built in a day. it'll take news corp shareholders several years and billions of dollars to replicate espn's success. i'm rick horrow. >> susie: tomorrow on nbr, how to do more with less. we visit one hospital that's using technology to do just that. and the economic and investment outlook for 2013-- we talk with gary thayer from wells fargo advisors. >> tom: we want to remind you about a special guest on nbr later this week. nbr founding co-an
